This build summarizes my CNC milling and laser engraving machine conversion from a dimensional lumber frame and electrical mess to an all aluminum frame with a safe and well constructed (IMHO) control system with the resources I had available.

This 1500mm tall Delta is a work in progress. The triangle corners are water jetted from 1" 6061 Aluminum, and are welded to 1" square tubing. The 1500mm OpenBuilds 20x20 V-Slot extrusions are held into the corner brackets by two stainless steel set screws per bracket. This printer will need to be reinforced with wall brackets due to the combination of height/materials.

My goal was to be able to enlarge my C-Beam with as many original parts as possible. I was able to recycle almost all of them with a only the two 500 mm rails left over. I used 1000 mm rails for the X Axis and I added another complete Y Axis assembly. I chose to keep it simple and I am very happy with the result!

My build is based on many different builds but pieced together into a unit specifically to suit my needs. The footprint, without motors, is around 500mm x 1000mm with a gantry height of around 250mm. I used a combination of C-Beam, for the linear transmission, and V-Slot for the base and gantry supports. Forged angle connectors were used for attachment and I utilized the C-Beam gantry cart kits with anti-backlash blocks for both Y axes, the X axis, and Z axis.

The aim of this build is to have a CNC that can cut a FULL sheet of wood when I need it to, but also shrink down and cut smaller sheets the rest of the time.
The prototype is based on an OX cnc but soon it will be completely custom using Openbuilds Parts

I have the demand to cut/etch tall pieces of material. For this reason, I have designed a machine with 500mm uprights with adjustable gantry height. This way I can raise/lower the sled and z-axis as needed. I've also chosen to use a linear C-channel assembly for the Z axis with the plate mounted to the gantry instead of the other way around. This will allow for maximum range of the z-axis. The parts list/BOM does not include motors/belts/pulleys or electronics.
